ARTHUR L. WALL, or BooNvILLE, NORTH CAROLINA.

AoETYLnNE-GAS GENERATOR.

To all whom t may concern:

Be it known that I, ARTHUR L. WALL, a citizen of the United States, residing at Boonville, in the` county 0f Yadkin and State of North Carolina, have invented new and useful Improvements in Acetylene-Gras Generators, of which the following is Va specification. A

This invention comprehends the provision of an apparatus forgenerating and storing acetylene gas, wherein use is made of vertically movable bells with one of which the carbid container is associated and adapted to be submerged within the water with a consequent generation of gas.

The invention provides an apparatus of this character by means of which gas can be economically produced in the generator and stored both therein and in the storage tank, from which latter the gas is initially discharged.

In carrying out the invention I construct the carbid container in a manner to prevent the generation of too much gas at one time, together with means for conveying the gas from the main generating compartment to the interior of the bell with which the container is associated, with a view of equalizing the pressure therein which controls the movements of the bell.

For the purpose of carrying these and other cordinate objects into effect, the preferred embodiment of the invention is illustrated and described, and embraced in the scope of the appended claims.

In the drawings forming part of this specication like numerals vof reference indicate similar parts in the several views and wherein i Figure 1 is a side elevation of the apparatus with certain parts broken away to show the interior construction.

Fig. 2 is a longitudinal sectional view through the apparatus.

Fig. 3 is a horizontal sectional view therethrough.

Fig.` 4.- is an enlarged detail view of the carbid container. y

The apparatus essentially consists of a plurality of closely associated tanks, both of which are adapted to be filled with water to a redetermined level, one of the tanks constituting a generator indicated at 10 and the other a storage tank indicated at 11. Rising centrally within each tank is a discharge pipe 12, the latter being branched olf Specification of Letters atent.

laterallyl as at 13 adjacent the bottom of their respective tanks and extended through the l corresponding side walls thereof and connected together by means of a valvev controlled pipe 14 through the instrumentality of-which communication is established between the pipes 12 and the respective tanks 10 and 11. A valve 15 is provided to control this communication, while rising from the pipe 14 is a supply pipe 16 common to both l of the discharge pipes 12 of the respective tanks.

Arrangedwithin each tank for vertical adjustment is a bell 17, which latter has secured on the interior thereof spaced spiders 18 which are connected by means of a centrally disposed hollow member 19 which receives the discharge pipe 12 of its respective tank, whereby the pipes 12 constitute guides for the bells as the latter are adjusted. Secured to two opposed walls of each of the respective tanksare cleats 20, while secured to the adj acentv walls of the bells 17 adjacent the bottoms thereof are similar elements 21 adapted to abut against the cleats 20 as the bells are moved upwardly, in a manner to be hereinafter described, tollimit the adjustment of the bells in this direction.

Forming a part of the bell 17 associated with the generating tank 11 is a receptacle 22 disposed centrally thereof, and projecting an appreciable distance'below the top wall of said tank. The receptacle is open at both ends, and thereby communicates with the interior of the bell, and is adapted to receive the carbid container 23 which latter is of corresponding cross sectional configuration as the receptable 22 and has its bottom and side walls perforated as shown. The carbid container is provided with a swinging yoke or handle 24 to facilitate the insertion ofthe container within or its removal from the receptacle 22 as the occasion may require, the container when positioned within the receptaclev resting upon the uppermost .spider`18 of the bell 17. Secured to two opposed walls of the container interiorly thereof are lugs 25 upon which rests a partition 26 dividing the container into two compartments solas to prevent too much gas being generated at one time, or in other words ywith one operation of the bell when it is lowered. A hollow tubular member 27 is passed centrally through the carbid container, extending through the partition 26, and is adapted to receive the discharge pipe 12 ont@ 'generating ank S0 that strega is generated a largeportion of the Same. Will be immediately conveyed through V-the 'pipe `12 of the tank 10 into the pipe 12.o f the tank 11 through the connecting pipe '121,'ands`ubsequently.stof-Gf. inthe bell 17 of the tank 111 The receptacle v22 is preferably Vformed with spaced walls 28 for the reception of thev sides 29 of a cover or closure 30 for the receptacle. The closure when in position is disposed slightly below the upperedge of the outer wall of the receptacle, and a rod 31 'passed transversely across the closure, and through. the alined openings in the outer wall 'of the receptacle fdr the purpose of holding the cover in place. The.spacebetween vvthe wallsI 28 of the receptacle' vis partially` lled with water to provide fa seal agY inst 'the escapenient of-ga's'from the recept'acle 22.

It is of course manifest that the bell 17 rof thelOf "ravitates to lowered position 'uIltil the carbidcontainer 23 is submergedin the water contained `v'vithin the tank, ,whereupon the'genera'tion of gas takesplace. As the gas is geifier'atedV it is 'received by 'the bell 17, whichv latter yunder a predetermined pressure isuelevate'dvto remove thecarbid 1coiltainer out of the water. As the carbid within thecontainer is 4still'saturated, a.' surplus amount of gas is'g'enera'te'd, this gasvis conveyed'throlrlghl the pipe 1 2 intoy the storage tank 11 in the manner' above stated.

The water 'then `'gravitate's into a substantially u -shaped drain pipe 37 coupled to the lpvverfend'f 'the supply pipe 16, and by reason of the formation of the drainpipe la ert'a'in amount of water is maintained therein t0 providea seat against the escapement of gas therethrough. It might here be stated that the component l'partsoffthe'y apparatus m'ay'beconstructed from any suitable material, and of any desired dimensions, while each vof the tanks 10 and 11 are'provided with a water drain cock 38.
